Design and Calculation of Flywheel of Jaw Crusher

The reinforcing rib is set in the position to withstand bending stress to meet the strength and stiffness requirements of the rack of the jaw crusher, which causes the complex structure of the jaw crusher. Since the rack force is relatively poor, the design is usually based on the size of the structure section which is approximately to the rack of the jaw breaker to approximately check its strength. The overall rack can be regarded as a static framework. The crushing force is acted on the front wall of the rack, while the acting force of the thrust plate is acted on the back wall. The supporting force is acted on the bearings of the two side walls. In order to simplify the calculation, we will not take the reaction forces on the sidewall into account and cancel the acting force acting on the thrust plate on the back wall of the rack. The force acting on the front and back wall is regarded as the concentrated force. According to the role, the force of the former and the posterior wall is calculated out.
The structure of the jaw crusher is symmetrical, so the load is symmetrical. According to this feature, cut the mechanism along the axis, the symmetric force of the point of symmetry is equal based on the role of symmetric load of the symmetrical bodies. The antisymmetric force is equal to zero. Due to the intermittent work of the jaw crusher, it is bound to cause changes in the resistance so that the load on the motor is uneven to cause the mechanical rate fluctuations. In order to reduce the nominal motor power and make the mechanical rate not fluctuate too much, the flywheel is installed on the eccentric shaft. The flywheels can store the energy in air travel and release energy in the working stroke, so you can make the motor load even.
